This invention relates to power transmitting mechanism and anvobject isto provide a simple and efficient transmission in which the drivinganddriven members are constantlyr f in engagement'and in which change inratio or speed of operation may be effected whether the machine isidleor in operation, thereby eliminating the necessity of moving themem.- bers relative to each other to obtain the d'esired speed or mannerof operation.

Other objects and advantages will herein-r after appear and theinvention is shown by way or" illustration in the accompanying drawingsin which- Figure 1 is a top plan view of the transmission with top orcover plate removed; Fig. 2 is an end elevation of the outside of thecasing for the mechanism; Fig. 3 is an end elevation of 'a dialvadjusted for one pound prints; Fig. i is a longitudinal sectional viewon the linel 4 4; of Fig?) showing the parts in position for packagingone pound prints of butter or the like; Fig. 5 is a section on the line5-5 of Fig. i showing a detail of the clutch; Figs. 6 and 7 are endelevations of a dial adjusted respectively for packaging quarter andhalf ypound prints; yand Figs. 8

respectively of. Figs. 6 and AZ'showing views the parts assume whereadjustments have been accordingly made.

The illustrated embodiment of this invention comprises a transmissionwhich tor purposes v'of illustration lout not oi' limitation will bedescribed in connection with its adaptation or use in connection with amachine ytor wrapping and packaging prints or bars of butter,oleomargarine, or materials of like form and consistency. Machines ofthis character are old in the art and reference is made to the patent ofJohn P. Aldrich and HowardZA. Morris, No. 1,6Q11-,203dated April 12, 192

It is desirable in these machines that certain adjustments be effectedso that it may be operated for packaging one-quarter pound bars,half-pound bars or one pound bars. As will hereinafter appearthisinvention provides a transmission which can be readily and convenientlymanipulated or adjusted Referring to the drawings, secured to the lmachine frame 1 1s a ytransmission casing composed oi the parts 2 and 3which are se cured together and'to the frame 1 by suitable bolts 4:.Having bearings in the transmission casing is a driving shaft 5 on whichare secured ythree different sized drivinggears 6,7 and 8. Power isimparted to the shat't 5 through a sprocket and chain connection 9a aswill hereinafter appear. j

-The driving gears 6, 7 and 8 mesh respectively with driven 'gears 9, 10and 11 which are coaxial with andV mounted on a driven shaft 12. It willbe observed that the gears 9, 10 and 11 are of different sizes. Theshaft 12 is tree from the gears 9, 1() and 11 which are rotatableindependently thereof.

Formed inthe shaft 12 are a plurality of sockets 13, one socket beingprovided for eachV of the gears 9,'10'and 11. Arranged Within eachsocket 18 is a clutch key 14 which is movable radially of the shaft 12.Each clutch Qey 1a is urged outwardly oiC its socket '13 byvra pairoit-coiled springs 15 disposed" in sockets 1G, thereby tending to torcea reduced' clutching end 17 into a keyway 18 formed in the adjacentdriven gear. it vwill thus be apparent that provided in sockets in thedriven shaft 1Q are clutchkeys individ# ual to each of the driven shafts9, 10 and 11 and spring means constantly vurges the keys into clutchingrelation with the driven gears.

. In the illustrate-d embodiment of the invention all oi' the clutchkeys 14 areretained out of engagementy with the driven gears except onewhich is released to enable the springs to snap` it into clutchingposition. As shown,.each keyla is formed with a longitudinal opening 19which is substantially rectangular in shape except the upper side' tangles. on the drawings, the three Lrisicos 2l lutch leys controll ig tle V1s 9, 'it and l another oli the clutch to operatively enga@ i iv iichthe remaining clutch niv ely retracted from clutchshait Q0 has a tongueand groove connection 22 with an extension 23, coiled springsuiaoimding` the extension and being so mounted as to urge the entensioninwardly into engagement with the control sha'"'t 20. Secured to theouter end oli the extension 23 on the outside ot the transmission casingis a dial 25 which is normally held by the spring in engagement with adisc 26. Displayed on the outside of the dial 25 are the letters P, HPand QP indi" cating respectively pound, halt pound and quarter pound.

An index 27 is provided on the disc 26 and in adjusting the dial 25 oneor another of the letters are brought into register with the in den inorder to operatively connect the gears for obtaining the proper ratiooioperation. ln the region of the index 27 is an outwardly en ending pinwhich m y entend into one ot the slots 28, one slotbeing provided in thedial for each of the numbers. rl`his insures that the proper adjustmentwill be made when the dial is turned to the desired position withrespect to the indef; 27.

lt Will readily be apparent trom the above that When the dial isturnedto one oi' the three positions designated thereon, one of thedriven gears will be operatively connected to the driven shaft. Figs. 3,i and 6 to 9 show the result of adjusting the dial 25 to the positionsmentioned. ln Fig. 3 the dial is turned so that P registers with theindex 27 and in this position, the control rod 2O is so positioned thatthe clutch key le for the driven gear 9 is released While the remainingclutch lreys are held out o1p4 engagement with the gears. ln Fig. Ll,the dial 25 is shown pulled out of engagement with the disc 26 prior tocompleting the adjustment, the disc 2G rotating with the shaft 12.

ln Fig. 7 the dial has been adjusted so that the transmission operatesproperly for' paclraging halt pound bars and, as shown in lEig. E), thedriven gear l() is clutched to the driven shaiit 12. Similarly llig. Gshows the dial Le adjusted to the quarter pound position in which, asshown in Fig. 8, the driven gear il is clutched to the shaft l2. Any ofthe above adjustments may be made While the machine is in operation orwhen it is idle.

he above described arrangement may be said to control the ratio otoperation of the bar feeding mechanism oi' the machine, it beingunderstood that the shaft l2 may be connected operate such mechanism..POW- er is also taken oil ot the driving shaft 5 by the sprocket andchain connection 30 Jfor operating other par ci' the machine. lt isapparent in view ot the diiierence in ratio, the speed oilthe sha-tt 1:2relative to the driving is hanged by the above. described adjustment ofthe dial 25.

it desirable to vary the speed ot' operation of drivi" shaft 5 at thetime the above described adj tments are eiifected. For e21- ample, whenthe dial is adjusted or quarter pound operation, the speed should bein-.

creased in order to facilitate the packaging operation and' when poundadjustment is made, the machine should operate at a slower rate oispeed. For this purpose a similar gear arrangement (the gears howeverbeing chosen of different sizes for obvious reasons) is provided'inWhich a. similar clutch arrangement is employed. lt is consideredsuilieient to point out that a dial 25a controls a driven shaiit 12a anda driving shaft 5a connected to a suitable source of power, the gears onthe driving and driven shafts being constantly in mesh. The clutcharrangement and operation is as above described. In this instance, thesprocket and chain connection 9a is connected to the driven shaft 12a sothat the change in speed of the driven shaft l2a is imparted to thedriving shaft 5. lt'vvill thus be apparent that When the dial 25 isadjusted a similar adjustment of the dial 25 is made so that the speedot operation of the iirst described gear arrangement is properlyregulated and this may be effected While the machine is in operation oridle.

A handle Wheel 3l having a pinion 32 enables manual adjustment oif theparts When desired.

lt is to be understood that altho this invention has been described inconnection with a machine for' Wrapping and packaging bars of butter andthe like, it is not limited thereto but is adapted for use in a varietyof machines, for example, it may be used to particular advantage in anygear driven machine tool or With some slight modiiication may be used asan automobile transmission. Numerous changes in details of construction,arrangement and operation may be effected Without departing from thespirit of the invention.

l/Vhat I claim is A transmission comprising a set of continuouslyrotatable driving gears, a. common ovver means for o eratin saiddrivin@` 2D gears, a set ofdriven gearsfconstantly in mesh With saidvdriving gears respectively,`
